a
LT-UC = lower tract urothelial carcinoma; RCC = renal cell carcinoma; UC = urothelial carcinoma; UTI = urinary tract infection; UT-UC = upper tract urothelial carcinoma.
b
Data are presented as No. (percent prevalence).
c
Defined as no cancer, stone, or UTI diagnosed.
d
Subgroup cancers may not add up to upper tract or lower tract numbers because of patients with multiple synchronous urothelial carcinoma diagnoses (ie, both renal pelvis and ureter in 3 patients with gross hematuria: 1 male and 2 female patients).
